解决addStringBody方法失效问题

public class WebService {
private String url;
private HashMap queryParameter;
private HashMap pathParameter;
private HashMap requestHeaders;
private WebServiceResponseListener webServiceListener;

public WebService() {
}

/**
* 构造函数，用于初始化请求的基本参数
* @param url 请求的URL
* @param queryParameter 查询参数
* @param pathParameter 路径参数
* @param _requestHeaders 请求头
*/
public WebService(String url, HashMap queryParameter, HashMap pathParameter, HashMap _requestHeaders) {
this.url = url;
this.queryParameter = queryParameter;
this.pathParameter = pathParameter;
this.requestHeaders = _requestHeaders != null ? _requestHeaders : getRequestHeaders();
}

/**
* 设置 WebService 响应监听器
* @param webServiceListener 监听器实例
*/
public void setWebServiceResponseListener(WebServiceResponseListener webServiceListener) {
this.webServiceListener = webServiceListener;
}

/**
* 发送 JSON 对象的 POST 请求
* @param requestTag 请求标签
* @param priority 请求优先级
* @param bodyParameters 请求体参数
*/
public void postJsonObject(String requestTag, Priority priority, Object bodyParameters) {
ANRequest.PostRequestBuilder postRequestBuilder = new ANRequest.PostRequestBuilder(url);

if (pathParameter != null) postRequestBuilder.addPathParameter(pathParameter);
if (queryParameter != null) postRequestBuilder.addQueryParameter(queryParameter);
if (requestHeaders != null) postRequestBuilder.addHeaders(requestHeaders);
if (requestTag != null) postRequestBuilder.setTag(requestTag);
if (priority != null) postRequestBuilder.setPriority(priority);

if (bodyParameters != null) {
postRequestBuilder.addApplicationJsonBody(bodyParameters);
}

postRequestBuilder.build().getAsJSONObject(new JSONObjectRequestListener() {
public void onResponse(JSONObject response) {
try {
webServiceListener.onSuccess(response.toString());
} catch (Exception e) {
e.printStackTrace();
}
}

public void onError(ANError anError) {
webServiceListener.onError(anError);
}
});
}

}

此问题来源于开源项目 amitshekhariitbhu/Fast-Android-Networking。
尝试使用 addApplicationJsonBody(bodyParameters) 方法，这在我的应用中解决了问题。
